  The information providing unit 43 provides provided information based on the content of the sensor information acquired by the sensor information acquiring unit 41. Moreover, the information provision part 43 changes the content of provision information according to the provision destination of provision information.

[Access Control]
For example, when the terminal computer 21 shown in FIG. 4 intends to acquire sensor information of a specific type among sensor information stored in the storage device 182, access for accessing the sensor information of the specific type. The request is transmitted to the sensor information management apparatus 101. At this time, for example, the terminal computer 21 includes its own identifier as transmission source information in the access request and transmits it to the sensor information management apparatus 101.

  Specifically, the wireless manufacturer TC21a, for example, in the csv file 191 shown in FIG. 3 stored in the storage device 182, a request for accessing the LQI of the column Col3 and the voltage value of the battery 15 of the column Col4, and An access request including its own identifier is transmitted to the sensor information management apparatus 101.

  The access control unit 47 in the information providing unit 43 can perform, for example, an access permission operation for receiving the request from the providing destination and providing the providing information to the providing destination. Specifically, for example, the access control unit 47 can receive an access request from the terminal computer 21 and perform an access permission operation that enables the terminal computer 21 to access sensor information based on the received access request. It is.

  In addition, the access control unit 47 provides, for example, one or more types of sensor information according to the destination of the plurality of types of sensor information stored by the storage device 182 as the provided information.

  More specifically, for example, when the access control unit 47 receives an access request from the wireless manufacturer TC21a via the communication unit 45, the access control unit 47 refers to the access permission table Tbla shown in FIG. The following processing is performed as the permission operation.

  That is, for example, the access control unit 47 confirms that “○” is included at the intersection of “wireless manufacturer TC21a” with “Col3” and “Col4” in the access permission table Tbla based on the content of the access request. It recognizes and judges that access permission should be given to radio | wireless maker TC21a.

  Then, the access control unit 47 performs, for example, an access permission operation that allows the wireless manufacturer TC21a to access the columns Col3 and Col4 in the csv file 191, and uses the LQI value and the voltage value of the battery 15 as provided information. To provide.

  Further, for example, the air conditioning management TC 21b transmits a request for accessing the voltage value of the battery 15 in the column Col3 and the battery 15 in the column Col4 and an access request including its own identifier to the sensor information management apparatus 101 in the csv file 191. To do.

  For example, when the access control unit 47 receives an access request from the air conditioning management TC 21 b via the communication unit 45, the access control unit 47 refers to the access permission table Tbla. Then, the access control unit 47 confirms that “x” is included at the intersection of “air conditioning management TC21b”, “Col3”, and “Col4” in the access permission table Tbla based on the content of the access request, for example. It recognizes and judges that access permission should not be given to air-conditioning management TC21b.

  Then, the access control unit 47 performs an access blocking operation for prohibiting access to the columns Col3 and Col4 in the csv file 191 by the air conditioning management TC 21b, for example. As described above, the access control unit 47 changes the content of the provision information according to the provision destination of the provision information.

  For example, when the access control unit 47 receives an access request for accessing the LQI of the column Col3 and the temperature of the column Col5 from the air conditioning management TC21b, the access control unit 47 sets “air conditioning management TC21b” and “Col3” in the access permission table Tbla. The following processing may be performed by recognizing that “X” and “◯” are included at the intersection with “Col5”. That is, for example, the access control unit 47 may determine that the access permission limited to the column Col5 in the csv file 191 corresponding to “◯” should be given to the air conditioning management TC21b, or “air conditioning management” in the access permission table Tbla. Since “x” is included at the intersection of “TC21b” and “Col3”, it may be determined that access permission should not be given to the air conditioning management TC21b.

[Notification of sensor information]
In the sensor information management system 302, for example, a state is assumed in which a schedule for notifying various sensor information at a predetermined time tn is set once a day.

  The notification control unit 48 in the information providing unit 43 can perform, for example, a notification operation for providing provided information to a providing destination regardless of a request from the providing destination. Specifically, for example, the notification control unit 48 can perform a notification operation in which sensor information is transmitted as provision information to a provision destination, that is, a transmission destination based on the notification permission table Tbln illustrated in FIG.

  In addition, the notification control unit 48 provides, for example, one or a plurality of types of sensor information according to the destination of the plurality of types of sensor information stored by the storage device 182.

  More specifically, the notification control unit 48 refers to the notification permission table Tbln held in the list holding unit 46 at a predetermined time tn when the sensor information should be notified, and performs a notification operation based on the contents of the schedule. The following processing is performed.

  That is, for example, the notification control unit 48 sends one or more types of sensor information according to the transmission destination based on the notification permission table Tbln among the plurality of types of sensor information to be notified according to the schedule via the sensor information acquisition unit 41. The sensor information acquired from the storage device 182 is transmitted to the transmission destination via the communication unit 45.

  For example, in the column of “wireless maker TC21a” in the notification permission table Tbln, the notification control unit 48 has “◯” in each row corresponding to “sampling timing”, “sensor ID”, “LQI”, and “battery voltage”. Recognizing that it is included, it is determined that each value included in the columns Col1 to Col4 in the csv file 191 should be notified to the wireless maker TC21a.

  For example, the notification control unit 48 acquires information on each value included in the columns Col1 to Col4 in the csv file 191 via the sensor information acquisition unit 41, and provides the acquired information as provision information to the wireless maker TC21a by e-mail. Send. Note that the notification control unit 48 may transmit the provision information to the terminal computer 21 by a method other than e-mail.

  Similarly, for example, in the column of “air conditioning management TC21b” in the notification permission table Tbln, the notification control unit 48 sets “O” in the rows corresponding to “sampling timing”, “sensor ID”, “temperature”, and “humidity”. "Is included, and it is determined that each value included in the columns Col1 to Col2 and Col5 to Col6 in the csv file 191 should be notified to the air conditioning management TC 21b. And the notification control part 48 acquires the information of each said value via the sensor information acquisition part 41, for example, and transmits each acquired information to the air-conditioning management TC21b by e-mail as provision information.

  Similarly, the notification control unit 48, for example, in the column of “production management TC21c” in the notification permission table Tbln, “sampling timing”, “sensor ID”, “temperature”, “humidity”, “illuminance”, “acceleration ( x) ”,“ acceleration (y) ”,“ acceleration (z) ”, and“ current ”are recognized in the rows corresponding to“ o ”, and columns Col1 to Col2 and Col5 in the csv file 191 are recognized. It is determined that each value included in ~ Col11 should be notified to the production management TC21c. Then, for example, the notification control unit 48 acquires information of each value via the sensor information acquisition unit 41, and transmits the acquired information as provision information to the production management TC 21c by e-mail.

[Alarm notification]
In the sensor information management system 302, for example, at least one of a measured value of acceleration (x), a measured value of acceleration (y), and a measured value of acceleration (z) has a predetermined threshold value Thx, Thy, and Thz. Assume a state in which an alarm indicating that an abnormality has occurred in the production apparatus in the facility 3 is set to be notified to the production management TC 21c when it exceeds each.

  The alarm determination unit 42 acquires information on the measured values of acceleration (x), acceleration (y), and acceleration (z) in the columns Col8 to Col10 from the csv file 191, for example, every predetermined time via the sensor information acquisition unit 41. The abnormal vibration of the production apparatus in the facility 3 is monitored based on the acquired information.

  For example, when the measured value of acceleration (y) exceeds a predetermined threshold value Thy, the alarm determination unit 42 recognizes that abnormal vibration has occurred in the production apparatus in the facility 3, and the measured value of acceleration (y) is abnormal. Is output to the notification control unit 48.

  When the notification control unit 48 receives an alarm request from the alarm determination unit 42, the notification control unit 48 refers to the notification permission table Tbln shown in FIG. 7 held in the list holding unit 46, and performs a notification operation based on the content of the received alarm request. The following processing is performed.

  That is, for example, in the row of “acceleration (y)” in the notification permission table Tbln, the notification control unit 48 sets “×” in columns corresponding to “wireless manufacturer TC21a”, “air conditioning management TC21b”, and “production management TC21c”. ”,“ × ”, and“ ◯ ”are recognized.

  Then, for example, the notification control unit 48 determines that alarm information including that abnormal vibration in the y-axis direction has occurred in the production apparatus in the facility 3 should be transmitted to the production management TC 21c, and produces the alarm information as provided information. It transmits by e-mail to management TC21c.

[Accessible sensor information without notification]
For example, the information providing unit 43 can provide providing information having different contents for each operation to the providing destination. In other words, the information providing unit 43 can provide providing information with different contents to the providing destination in the access permission operation and the notification operation, for example.

  Referring to FIGS. 6 and 7 again, for example, as shown in access permission table Tbla shown in FIG. 6, production management TC 21c can access the LQI value and the voltage value of battery 15 in the access permission operation. On the other hand, for example, as shown in the notification permission table Tbln, the LQI value and the voltage value of the battery 15 are not notified to the production management TC 21c in the notification operation.

  For example, when the communication quality in communication between the access point 161 and the sensor 151 is poor, that is, when the value of LQI is small, the collection device 181 receives sensor information including content different from the measurement result by the sensor 151 from the access point 161. Therefore, an abnormal value measurement result may be written in the csv file 191.

  In addition, when the voltage of the battery 15 in the sensor 151 is low, the sensor element 14 operates differently from the normal operation, and the measurement result by the sensor 151 may show an abnormal value.

  In contrast, for example, in production management TC21c, sensor information that is normally sent once a day, specifically, at least one of measured values of temperature, humidity, illuminance, acceleration in each direction, and current is measured. When one is abnormal, the access request can be used to receive the LQI value and the voltage value of the battery 15 from the sensor information management apparatus 101. Therefore, the communication quality between the access point 161 and the sensor 151, and the sensor 151 The operating state can be quickly grasped.

  Thereby, for example, it is possible to quickly grasp whether or not the cause that the value indicated by the sensor information is abnormal is the communication quality or the operation state of the sensor 151.

  In other words, information that is necessary in the normal state is subject to periodic notifications, and information that is necessary in an abnormal situation is not subject to periodic notifications, so that information that is not necessary in the normal state can be accessed periodically. Can be avoided, and necessary information can be quickly acquired in an abnormal state. Therefore, the convenience of the user of each terminal computer 21 in the sensor information management system 302 can be improved, and the information transmission efficiency can be improved.
